How to Examine a Mole

Examining a mole is one way you can detect the form of skin cancer known as melanoma. Here are some guidelines about what to watch for, based on the American Cancer Society's recommendations.

Instructions

Difficulty: Easy

Things You’ll Need:

• Mirrors

1. Look for asymmetry - that is, see whether the shape or color of one half of the mole does not match the other.
2. Note any irregular borders, such as blurred edges.
3. Examine the mole to see whether its color is no longer uniform.
4. Be alert to any increases in the size of your mole, especially if its diameter is greater than 6mm.
5. Check for any spread of pigment from your mole to the area of skin surrounding it.
6. Note any redness in your mole, as well as changes in the surface, such as crusting or oozing.
7. Be alert to changes in the sensation of your mole, such as pain or itchiness.
8. Contact your doctor is you notice any of the above or if you have other concerns about a mole.

Tips & Warnings

• Use a mirror to view moles on your back and other hard-to-see areas.
• Examine your body regularly to become familiar with the size, shape and color of your moles, blemishes and birthmarks. This can help you be alert to changes that might indicate melanoma growths.
• Ask your doctor if you should have regular examinations by a dermatologist, especially if you spend a lot of time in the sun or have fair skin or a family history of skin cancer. The doctor can make a body map of your moles, blemishes and birthmarks, thereby tracking any unusual growth or changes.
